Title: Method for collecting mowed lawn and  apparatus for effecting the same
Inventor: TAKAHASHI KATSUHIKO
IPC: A01D57/12

Abstract: ABSTRACT OF THE DISCLOSURE The present invention is directed to an apparatus and method for collecting the discharged grass clippings of a lawn mower.  The lawn mower includes a discharge opening at the lateral side or the rear side of the lawn mower.  Grass clippings are directed through the discharge opening to a conveyor member, thereafter the clippings are deposited in a catcher.  The present invention does not require a high speed air flow to discharge the grass clippings.  Further, since the grass clippings are discharged by a conveyor member into the top opening of a catcher the level of grass clippings positioned in the catcher may readily be observed so that it is very easy to determine when the catcher should be emptied.

Abstract: ABSTRACT OF THE DISCLOSURE       Disclosed is an improved drum mix plant which includes a rotating  elongate inclined mixing drum having openings at each end for introduction and removal of asphalt-aggregate material from the drum, an adjustable burner at one end of the drum for heating the contents thereof, ducts for removing heated gases from the drum and directing a portion of said gases to a baghouse for removal of particulate material and for directing the remainder of said gases to a manifold surrounding the burner for mixing and cooling of the higher temperature gases of the burner.  Dampers within the ducts may be opened and closed in response to temperature sensors placed adjacent the entrance point and the exit point of the asphalt-aggregate material in the drum thereby regulating the volume of gases flowing through the drum.  The sensors may also regulate the amount of fuel supplied to the burner and thereby control the degree of heating of recycled gases.

Abstract: ABSTRACT OF THE DISCLOSURE     "Method of Meat Tenderizing", is a tenderizing process in which a calculated amount of wine or spirits, relative to the size of the dead animal ie. rabbit, sheep, cattle, swine, horse, deer, moose and the like is injected into the vascular system under pressure from a pump apparatus when the animal is in a post mortem state of primary flacidity and prior to any debleed-ing or mutilation of parts via a major artery and the intra-vascular pressure is allowed to build until the venous system is distended and at that point a major vein is opened and allowed to drain.  The solution is continually pumped through the vascular system until all the blood is flushed from the system.  The pro-cess is completed once the arterial, capilliary and venous systems are flushed and saturated with wine or spirits and the animal is eviscerated and the carcass is allowed to hang at 38°F, while the wine or spirits is allowed to react on the tissue resulting in a thorough tenderizing of the meat for eatable purposes.

Abstract: ABSTRACT OF THE DISCLOSURE    A handle operator slide and a motor operator slide are individually coupled with a charging mechanism to independently charge charging springs thereof.  The charging mechanism is operative to charge the springs of a contact operating mechanism as the charging springs discharge.  The charging mechanism includes a prop controlled by the condition of the operating mechanism to releaseably sustain the charging springs in a fully charged condition, while the operating mechanism includes a hook to releaseably sustain the breaker contacts open against the urgence of fully charged operating mechanism springs.  Consequently, the circuit breaker is capable of executing multiple contact opening and closing operations without recharging the charging springs by wither the handle or the motor via their respective slides.

Abstract: 3.3.1980                   1                     PHN 9491 ABSTRACT:     A stepping motor with a first and a coaxially disposed second stator section, which stator sections are axially separated by a coaxially disposed permanent-magnetic ring. On the inside each stator section terminates in two coaxially disposed annular systems of teeth. The systems of teeth of each stator section have been shifted nominally by 1/2 tooth pitch relative to the rotor teeth and the systems situated on the outside relative to the permanent magnetic ring as well as the systems of teeth situated on the inside relative to the permanent magnetic ring exhibit a nominal mutual shift relative to the rotor teeth of 1/4 tooth pitch. Stepping angle errors in this stepping motor can now be eliminated to a high degree by symmetrically correcting the displacement of the outer systems of teeth relative to each other and/or the displacement of the inner systems of teeth relative to each other.

Title: Apparatus for the measurement of density-  thickness by use of radiation
Inventor: BUCHNEA ALEXANDER
IPC: G01D3/02
Filed: 1980-06-20
Granted: 1983-01-25
Abstract: Abstract of the Disclosure Apparatus for accurate measurement of the density-thickness or mass per unit area of a material placed between a radioactive source and an ionization chamber, in which the apparatus is calibrated by using a plurality of standards of known mass per unit area or basis weight to provide a relationship between basis weight and the output current of the chamber which includes at least terms of the second order and preferably includes terms of the third and higher orders.  The accuracy is increased by enclosing the major portion of the radiation path in airtight chambers, leaving only enough of the path exposed to the external atmosphere as is necessary to provide a working air gap through which the material may pass.  The airtight chambers are of sufficiently rigid construction that the density of the gas therein is substantially constant and independent of ambient temperature and pressure variations.  The accuracy is further increased by measuring ambient temperatures and pressure fluctuations, and linearly compensating the computed basis weight for resultant density variations in the small working air gap.

Abstract: ABSTRACT      Thermoplastic polyamide polymers such as nylon 6/6 are rendered fire retardant by the addition of an effective amount of a tris-(3-hydroxyalkyl) phosphine oxide of the formula   wherein R1, R2 and R3 are any radical selected from the group consisting of hydrogen, phenyl and alkyl radicals of 1 to 4 carbon atoms and n may be 1, 2 or 3.  These fire-resistant polymers are useful in the internal circuitry of appliances, business machines, terminal strips, connectors and blocks.  Nylon fibers thus made flame retardant are useful because they are more resistant to dirt and static build up and are less hydrophobic, thus improving wearability.

Abstract: ABSTRACT OF THE DISCLOSURE A pincushion distortion correction saturable reactor is a saturable transformer comprising a core having four legs, controlled and control coils coupled to the core legs in a perpendicular relation to each other.          The core gap for the controlled coil is provided in an unbalanced form, and a parabolic current at the vertical scanning frequency (for at horizontal scanning frequency) containing a superimposed DC component is supplied through the controlled coil to modulate the inductance of the controlled coil.   The inductance of the controlled coil is thus reduced in a region where the magnetomotive force produced by the control coil is greater than that of produced by the control coil to preclude deflectional distortion in the neighborhood of the center of the reproduction on the screen and improve the horizontal linearity.
